How to Clean Spots on the Hood?

[AxelLynn]

Water stains on the car can be cleaned with a cleaning wax, provided that the stains are still in their early stages and have not penetrated the paint. If water stains cannot be wiped off, it indicates that they have already penetrated the paint. In such cases, cleaning wax won't work, and polishing is the only solution. While polishing can restore the paint surface, it is a consumable maintenance process. Polishing reduces the thickness of the paint, so it's best to keep the number of polishing sessions to a minimum.
